"Nobody knew" /s Identify them in big bold red colors. Make their history publicly auditable (when they joined, how their followers/following pattern looks like, what their posting pattern looks like, what topics/hashtags do they use most frequently, what their network of connection looks like). Restrict the hell out of them as to what/how many actions they can do every month (un/follow, post, rt, like, report) so that they become slow by design.
